Reduce Image Size in KB

Reduce Image Size in KB makes a photo or signature fit the file size and dimensions an application form asks for, in one step. Set a range such as 10–20 KB or 20–50 KB, and optionally the width and height in pixels or centimetres (with DPI). The tool keeps the best quality that fits under the maximum. If a small image is still under the minimum at the best quality, it adds blank data inside the file so it reaches the minimum without changing the picture. It never shrinks the picture without telling you. JPG, PNG, WebP and iPhone HEIC work. Everything runs in your browser; nothing is uploaded.
